General Seiko mechanical watches adjust the time, calendar and day of the week in the same way. The watch has two settings, the first is calendar and day of the week. Adjust the day of the week up and the calendar down. The second gear is to adjust the time. The specific steps are introduced below:

1. Pull out the first gear to adjust the date, and then pull out the second gear to adjust the time. Pull out the first gear first to prepare to adjust the date;

2 , the watch crown is turned down and turned down respectively to adjust the day and date. For example, today is Sunday, March 4th, you can first adjust the day and date to yesterday's Saturday, the 3rd;

3. Then pull the crown out to the second position to adjust the time and rotation. Turn the watch hand clockwise for one or two turns until you can see that when the hand reaches around 12 o'clock, the day and date jump to Sunday and the 3rd respectively. This means that the watch time enters 1-12 o'clock in the morning. ;

4. Follow the usual method of adjusting the time of a watch. After turning the hands once, the watch time will enter 1-12 o'clock in the afternoon. You can then adjust it to the current correct time, and you are done. . In more than 90 minutes, the watch will automatically jump to Monday the 5th.

Extended information:

SEIKO, which has a century-old history, develops and operates the Chinese market with the brand definition of "innovation and refinement". Its novel, fashionable and classic watches are deeply loved by people from all walks of life in the country. Seiko sales points and service stations in more than 20 cities.

Long-term energy storage: By using a new material mainspring, the original traditional mechanical watch can be extended from 40 hours to 72 hours in a fully wound state.

Quick winding: SEIKO's unique "magic lever" winding system is nearly 30% faster than most traditional mechanical winding systems.

High accuracy: The three-level synchronous modulation speed controller ensures an accuracy of ± 1 second/day (± 15 seconds/month), while the accuracy of the chronometer mechanical watch is -4 ~ + 6 seconds/day.

Scanning smooth hands: The one-way movement inside the movement allows the hands to move smoothly without any stagnation, reflecting the true flow of time. Making SPRING DRIVE the only watch whose pointer movement can reflect the true flow of time.

In addition to the above-mentioned outstanding features, SEIKO's top manufacturing technology also ensures the top quality of its products. The Spring Drive series is assembled entirely by hand by the best watchmakers in SEIKO EPSON, one of the few comprehensive manufacturing plants in the global watch industry (all parts of the movement are produced and assembled by itself).

SEIKO firmly believes that watches are personal friends. The best watch should have a tacit feeling of fit with the wearer, and the functions provided by the watch can bring the wearer a sense of security, reliability and emotional satisfaction. SEIKO's technological research and development is dedicated to the development of "humanized technology." Humanized technology creates an interactive connection between watch products and wearers.

Spring Drive

In 1977, a young engineer from SEIKO started a dream. How to make a "long-lasting watch"? His goal Yes: This watch is driven by a spring and has an accuracy of plus or minus 1 second per day. This is a high level of accuracy that only sophisticated electronic watches can achieve. This engineer, Yoshikazu Akahane, is a man of firm belief and dedication. It took him 28 years, experienced countless setbacks, and produced no less than 600 test products. After achieving breakthrough technological innovations in every aspect of watchmaking, he and his team finally succeeded. In 2005, the era of Spring Drive has arrived!

Four Outstanding Features of Spring Drive By improving four key areas of the luxury watchmaking process, Spring Drive achieves its sophistication, precision , reliability and durability.

The high-precision "three-level synchronous modulation speed controller" synchronously controls and regulates the output of three different energy sources generated by the spring, mechanical energy, electricity and electronic magnetic energy. Instead of the traditional mechanical watch speed control system and escapement device, the innovative speed modulation system of one-way rotation makes the watch inherently more stable, durable and accurate.

Spring Drive is accurate to ±1 second per day.

Scanning Smooth Pointer The Spring Drive movement does not have a balance wheel escapement system. The entire machine always rotates in one direction, giving the pointer a unique scanning sliding movement. Spring Drive is the only watch in the world that truly embodies the continuous flow of time.

Long-term energy storage The new mainspring can provide more powerful, stable and long-lasting power. SEIKO has developed a special alloy material that is durable, resistant to high temperatures and corrosion, and can generate more energy. Spring Drive has 72 hours of energy storage even when the chronograph function is used continuously.

Quick winding In 1959, SEIKO invented a special component of the mechanical watch winding system - the "magic lever". No matter which direction the pendulum swings, the energy generated by each swing can be effectively used, thus greatly improving the efficiency of the automatic winding system! Nowadays, the new magic lever winding system is directly driven by the bearing of the pendulum, making winding more efficient than before.

Magic lever The magic lever is developed from the automatic winding system first developed by SEIKO in 1959.

In SPRING DRIVE, the new "magic lever" winding system is set directly on the axis of the pendulum, thus making the spring winding more efficient and the power storage time longer.

Spring Drive Chronograph Watch

The SEIKO Spring Drive system provides a perfect foundation for high-end chronograph watches, because the elapsed time during the timing process can be accurately measured. Capture and point out rather than pointing to the nearest tick point. It is equipped with an accuracy of ±1 second/day and can time up to 12 hours. It is also equipped with a "vertical cross-link device" and a "column wheel" to ensure the accuracy of the buttons. It can be called one of the best chronograph watches in the world. one. Fully hand-assembled, with 416 parts, 50 jewels, 140 oiling points, and using 5 different lubricants, the Spring Drive chronograph still has a 72-hour power reserve function even when the chronograph function is activated.
